Tuning into the Musician Seamounts

During their 2015 Hohonu Moana expedition, the NOAA Ship Okeanos Explorer discovered and mapped an unnamed seamount in the Central Pacific Ocean Basin (shown in the image above). The ship and scientists are now returning to this region, “Musician Seamounts”, to conduct additional mapping and remotely operated vehicle (ROV) operations over two consecutive cruises. These efforts will be focused north of the Hawaiian Islands, close to the Papahānaumokuākea Marine National Monument (PMNM).

The Scintillating Sea Life of Pao Pao Seamount

The NOAA Ship Okeanos Explorer had an amazing dive March 9, 2017 on Pao Pao Seamount, an underwater mountain in the Tokelau Seamount Chain in the South Pacific. Continue reading The Scintillating Sea Life of Pao Pao Seamount

What is an ROV?

If the ocean is so unfathomably wide and deep, how can scientists possibly hope to do any more than dip our noses beneath the waves to explore? Luckily, engineers have adapted machines to reach areas of the ocean that would never be possible with a human alone. This is where remotely operated vehicles, or ROVs, become essential tools of discovery.

To use an ROV, three pieces of technology are crucial. The first is the ship. This is where the scientists are conducting their research, and where the ROV pilot maneuvers the vehicle. The second piece is the tow sled. This piece of technology is used to absorb all of the movement associated with waves and currents, allowing the ROV to be stable. Lastly, is the ROV itself. The ROV and sled are tethered to their research vessel via fiber optic cabling. Through this system, the pilot can maneuver the ROV safely from the ship.

ROVs are designed to withstand the extreme cold and pressure of the deep ocean without malfunction. They are typically either colored yellow or white to stand out against the blues of the ocean, and are built out of materials that are resistant to many atmospheres of compression. ROVs are also balanced with the dense components on the underside, and the flotation portion on top, to offer more stability as it traverses the deep ocean. ROVs can also be equipped with a variety of tools to help them explore efficiently. Since the ocean continually gets darker the deeper one goes, all ROVs are equipped with extremely bright lights. Each ROV has a few high definition cameras that allows us to watch the ROV. They also have two lasers that are used for scale, generally they are 10 cm apart. Most vehicles have biofeedback manipulator arms that are used to gather samples. Some vehicles have a sample box to take bring samples up to the surface for more research.

These incredible machines are vital for scientists to explore parts of the ocean that would not otherwise be seen by human eyes. Tune into the live video feeds below to see ROVs in action, along with more exciting content!

Introducing the Newest U.S. Academic Research Vessel: R/V Sally Ride

Named in honor of the first woman to travel into space, Dr. Sally K. Ride, the R/V Sally Ride is the newest of the United State’s Academic Research Vessels (UNOLS).  Operated by the Scripps Institution of Oceanography at the University of California, San Diego, in cooperation with the Office of Naval Research (ONR), Sally Ride represents the new Ocean Class of research vessels. The 238-foot ship features seafloor mapping systems, doppler radar for mapping deep water currents, 2,035 square feet of lab space, and telepresence technologies.

Telepresence on the R/V Sally Ride

From November 28 to December 5, 2016, the Inner Space Center (ISC) supported a science verification cruise for the R/V Sally Ride, one of two, new vessels in the U.S. Academic Research Fleet.  These short cruises are intended to test the ship, crew, and science systems to make sure that all are in proper working order before the ship  departs for its first research expedition. The Sally Ride was named after the late Sally Ride, the first American woman in space, who was part of the space shuttle Challenger crew in 1983.


The ISC team tested
the ship’s capabilities to support the Jason remotely operated vehicle (ROV) system as well as ship-to-shore telepresence technologies and protocols that will enable shore-based participation during ROV dives. Director of the ISC, Dr. Dwight Coleman, installed a mobile telepresence unit (MTU) on board. This unit allows for any ship to have telepresence capabilities.

ROV Jason deployed off the R/V Sally Ride.

During the cruise, ROV Jason was used for a variety of exploration activities. Geophysicist, Dr. Mark Zumberge, and his group from the Scripps Institution of Oceanography, used Jason to attach geophysical sensors to the sea floor. Dr. Lisa Levin, also from Scripps, used the ROV system to continue biological survey of the seafloor around the Del Mar methane seep near San Diego, CA.

Along with ROV operations, the R/V Sally Ride was able to connect to the Birch Aquarium. Amanda Netburn, Bruce Applegate, and Dwight Coleman hosted live  broadcasts to the aquarium’s new Sally Ride exhibit.

Rhode Island Shipwrecks Recap

From September 2nd, to September 6th, several members of our URI GSO Inner Space Center team sailed aboard the R/V Endeavor. We were joined by scientists (from the URI Graduate School of Oceanography), high school teachers, and members of the United States Coast Guard Academy. Everyone onboard came out to sea for our Rhode Island Shipwrecks project.

Sea Life and Salt

The NOAA science team stumbles upon an underwater salt lake, also known as a “brine pool.”

The NOAA Ship Okeanos Explorer has been diving its ROV, D2, in the Gulf of Mexico this April. Here is a video clip of one of their awesome encounters in the depths of the Gulf. A brine pool is literally an undersea lake. The contact between salty ocean water and much saltier water (brine), means denser water liquid separates from the less dense ocean water. This saltier fluid sits and “pools” on the bottom. It’s so salty that it will erode the sediment it lies on, forming these pools. If any deep sea dwellers happen to stumble into this pool, they have no chance of getting out (and definitely no lifeguards to help!). It’s a geological anomaly for sure, but it’s a nightmare for any biology living in this normally pitch-black environment. However, those creatures that can acquire some “waterfront” property, while anchoring themselves safely, may reap some serious benefits.

ROV

What’s an ROV? An ROV is a remotely operated vehicle used by research teams as a submersible.

ROVs are tethered to ships. They are controlled by a remote either on ship or land.  They are powered by the ship. For the purpose of ocean exploration, the ROVs we use have high definition video cameras that record the live streaming video.
